A compact heat exchanger is provided, in which multiple streams can flow within the same layer or layers, and different fluids may flow in alternating channels within the same layer as well as flowing in alternating layers. Having fluids in alternating channels&#x2014;as compared to only alternating layers within the same layer&#x2014;increases the direct surface area between the fluids (the primary surface area) for heat transfer, thereby increasing the rate and efficiency of heat transfer. Methods of making and using the heat exchanger are also provided.

Compact heat exchanger with alternating fluid channels

A system for producing hydrogen features a reactor including a reaction channel adapted to receive a reaction stream including a mixture of supercritical water and a hydrocarbon fuel. A catalyst is positioned in the reaction channel so that a product stream containing hydrogen is produced by a reaction in the reaction channel when the mixture is exposed to the catalyst; wherein the catalyst contains a catalytically active metal and a promoter in a metal format, selected from the group consisting of potassium, sodium, rubidium, lithium, cesium, beryllium, magnesium, calcium, strontium, and barium.

Catalysts, system and method for hydrogen production

A device for processing fluids includes a number of fin layers with a number of plates separating the fin layers so that a fluid flow passage is defined through each fin layer. A first fluid inlet is in communication with a first end portion of the fluid flow passage, a first fluid outlet is in communication with a second end portion of the fluid flow passage, a second fluid inlet is in communication with the second end portion of the fluid flow passage and a second fluid outlet in communication with the first end portion of the fluid flow passage. The fluid flowing through the second inlet is subjected to a shearing action by the fin layers so that mass transfer to the fluid flowing through the first inlet occurs. The device may be used for both liquid-liquid processes, such as extraction, or gas-liquid processes, such as adsorption, absorption or desorption and reactions.

Plate fin fluid processing device

A reactor, system and method for producing hydrogen features a reactor containing a heating stream channel and a hydrogen channel with a reaction channel positioned there between. A heat transfer sheet separates the heating stream channel and the reaction channel and a porous support plate separates the reaction channel and the hydrogen channel. A membrane constructed from palladium, vanadium, copper or alloys thereof covers the porous support plate. The heating stream channel receives a heating stream so that heat is provided to the reaction channel through the heat transfer sheet. A catalyst is positioned in the reaction channel and the reaction channel receives a reaction stream including a mixture of supercritical water and a hydrocarbon fuel so that hydrogen is produced in the reaction channel and is passed through the membrane into the hydrogen channel. The hydrogen separation may alternatively be accomplished in a separator device distinct from the reactor via either a membrane or pressure swing adsorption.
